UPHOLSTERY SPRING CONSTRUCTION.

" Specification of Letters Patent.

Patented Apr. 8, 1919.

Application filed February 10, 1919. Serial No. 276,225.

To all whom it may concern:

Be it known that I, LEONARD A. YOUN% a e.- troit, Wayne County,Michigan, have in vented certain new and useful Improvements inUpholstery Spring Construction, of which the followlng is a full, clear,and exact specification.

In the use of sprin seats, it is advisable that the springs be a ordedsuch support as.

to carry the load easily under normal shock, and at the same time becapable of resisting severe impacts, as when the vehicle in which theconstruction is used is traversing rough roads, in such a manner as tocushion the occupant against unnecessary jolting.

This invention includes means whereby the springs are not only givenample support, but also are yieldingly maintained, so that the occupant,if the springs are fully compressed, does not feel the jolt of a rigid,or non-elastic base, such as is usually used to support springs.

A further advantage of the construction is the shielding of the interiorfrom dust and lodgment of foreign articles when the seats are removed,while the appearance is good and the parts assembled with a minimum ofcost of labor and material.

The invention consists in the matters hereinafter set forth, and moreparticularly pointed out in the appended claims.

In the drawings:

Figure 1 is a plan view with the upholstery covering removed andpartially broken away of a construction that embodies features of'theinvention:

Fig. 2 is a view in section and in detail of a portion of theconstruction;

Fig. 3 is a view in section and detail showing a modification of theconstruction;

Fig. 4 is a plan view of a seat showing the application of theupholstery, partially broken away;

Fig. 5 is a view in section and in detail showing a modification of thebase;*

Fig. 6 is a view in form of securing and holding band,

Referring to the formed of transverse strips 2 'of wood or light, thin,resilient material, that are bound along front end marginal portions bya U shaped strip 3 of sheet metal that is detail showing one drawings, abase-1 is clenched upon them, and is carried around the corners, as at iif desired, while a rear strip 5 similarly secures the rear end marginalportions together.

The assembled base 1 is given the contour desired to have it meet therequirements of a frame of any desired dimensions an shape.

A plurality of upright spiral springs 6 are mounted on the base strips.These may be conoidal as indicated, or they may be of the hour-glasstype, or of any preferred design suitable for the purpose. The base turn8 of these springs may be stapled, or otherwise secured to the strips ofthe base; but preferably they are each held in pliable flat metal bands9 that are supported on the base. Tacks may be used to hold the stripsinposition, or in the preferred form of construction, the end portionsof the bands are cut transversely and spurs 11 are bent down therefrom,and riveted through the base strips. Likewise the method of securing thesprings to the flat bands may be varied as desired. As herein indicated,each base coil 8 is passed under a tongue 13 struck up from the face ofthe band, and beneath the band and between the band and a tongue 14, thetongue being clenched as desired.

A rim frame 15 may encircle the outer springs and is secured to theouter upper turns'thereof, clips 17 being used, or other suitable means,to secure the parts together.

' The tops of the springs may be stayed by cross-connections, or thelatter may be omitted.

'The usual upholstery filling or cushion body 18 is laid on the springsand a cover 19 placed thereon with a depending apron 20 cured, whilebelow, a groove is used to retain dec the enlarged or welt edge 5 of theapron, the latter being inserted therein and the strip clenched upon itin the usual manner, or the groove of the strip may merely afford aninterlock engagement with the inserted welt. When it is desired toprevent any sidewise movement of the individual resilient strips 2, theU-strips 3 and 5 may be crimped between the strips, as shown at 26 inFig. 5.

As a result of this construction, the spring seat has a closed base,which afi'ords perfect support for the springs and gives ease to theoccupant when the resilient springs yield to a sudden jar, which bringsthe tops of the springs of the upholstery into contact with the base,the latter cushioning the shock, since the strips bend readily andindividually, as they are connected together at the ends only.

Furthermore the base is a shield that prevents any large foreignsubstance working into the springs and gettingentangled therewith, whilethe finish is such that the unsightly underside of the upholstery isconcealed when the spring seats are removed.

Obviously, changes in details of construction may be made withoutdeparting'from the spirit of the invention, and I do not care to limitmyself to any particular form or arrangement of parts.

What I claim is 1. In an upholstery spring construction a base formed ofresilient strips, means securing the strips along the end marginsthereof to form a closed seat bottom, springs mounted on the base,upholstery on the springs and a cover for the upholstery having adepending apron secured along the, margin thereof to the base.

2. In an upholstery spring construction a base formed of resilientstrips in juxtaposition, means securing together along the end marginsthereof, upright coil springs, and a cover for the upholstery having adepending portion engaged along the lower margin thereof to the stripsecuring means.

3. In an upholstery spring construction, a base formed of resilientstrips in juxtaposition secured along the marginal end ortions thereofby a sheet metal strip, uprigl it spiral springs mounted on theresilient strips, upholstery on the springs, and a cover thereon havinga depending apron secured along the margin thereof to the base.

4. In an upholstery spring construction, resilient base strips injuxtaposition, U-strips embracin the marginal end portions of the stripsand securing them together, upright spiral springs mounted on theresilient strips, upholstery on the springs and a cover therefor havinga depending apron secured along the lower margin to the base strips.

5 In an upholstery spring construction a resilient base, sheet metalbands supported on the base, upright spiral springs supported on thebase and interlocked with the bands, upholstery on the springs, and acover for the upholstery with a depending margin portion secured to thebase.

6. In an upholstery spring construction, resilient strips, U-stripsembracing the marginal end portions thereof and securing the strips injuxtaposition, sheet metal bands on the resilient strips, upright spiralsprings supported by the base strips and secured by the bands,upholstery on the springs and a cover for the upholstery having adepending portion, the margin of which is secured to the base strips.

7. In an upholstery spring construction, resilient base strips injuxtaposition, binding strips, each having a pair of flanges betweenwhiclrthe end marginal portions of the resilient strips are secured,sheet metal bands secured on the resilient strips and provided withstruck out spring retaining portions, upright spiral springs the baseturns of which interlock with the struck out portions of the bands, thestrips affording support for the bands and springs, and upholstery onthe springs. v

8. In an upholstery spring construction, resilient spring supportingstrips, binding strips each having a pair of spaced flanges betweenwhich the end marginal portions of the resilient strips are secured injuxtaposition, the binding stripsbeing formed with a Welt receivinggroove, sheet metal bands lying on the resilient strips, upright springsinterlocking with the bands, upholstery on the springs, and a covertherefor having a depending portion, a margin of which is secured in thewelt receiving groove.

9. In a spring seat construction, a resilient base formed of strips injuxtaposition secured along the margin end portions thereof by bindingstrips which embrace them, sheet metal bands on the resilient stripshaving spurs struck from them that penetrate the strips and secure thebands in position and upright spiral springs secured in position on 11.In an upholstery spring construction,

resilient basestrips in juxtaposition, U-strips embracing the marginalend portions of the strips and securing them together, a Welt receivinggroove in each U-strip, upright springs on the strips, upholstery on thesprings, and a cover therefor having an ties thereof only, each stripbeing free to flex apron with welted edge secured in said between theend securing means independgrooves. ently of the adjacent strips,upright coil 10 12.
